Linux OpenGL: Ubuntu 13.04/13.10 vs. Fedora 19/20
CoreBreach shows just how faster Ubuntu 13.10 can be over Ubuntu 13.04 for Intel Haswell graphics performance. Fedora results aren't available for this GNUstep-based game due to dependency issues.
With the upgraded graphics stack in Ubuntu 13.10, the Nexuiz performance is now in line with Fedora 19 and Fedora 20.
While Fedora 20 currently is in a debug state, its performance wasn't negatively affected compared to Fedora 19 at least in many of the benchmarks used.
